We all know about Type 1 and Type 2 diabetes, but have you heard of Type 3? It's not directly related to blood sugar levels in the same way, but mounting research suggests a strong link between insulin resistance in the brain and Alzheimer's disease. Some researchers even refer to Alzheimer's as "Type 3 Diabetes."
Here's the connection: Insulin, essential for regulating blood sugar, also plays a crucial role in brain function. It helps neurons absorb glucose for energy and supports memory formation. When the brain becomes resistant to insulin, it struggles to get the fuel it needs, leading to cognitive decline characteristic of Alzheimer's. This insulin resistance can trigger amyloid plaque formation and tau tangles, the hallmarks of the disease.
While more research is needed to fully understand this connection, recognizing the potential link between metabolic health and brain health is crucial. Maintaining a healthy lifestyle, including a balanced diet and regular exercise, may be vital not just for preventing traditional diabetes, but also for protecting your brain's long-term health. This means eating plenty of fruits, vegetables, and healthy fats, and avoiding processed foods and sugary drinks.
